Try pressing 1 and 7 at the same time
The LCD will show "OPC belt 1. Reset 2. Exit
Select 1 to reset the life counter.

This is supposed to be done when replacing the drum unit...but I've found that I can get 1.5 to 2 lifespans from a single unit.

I just install a new opc belt in a xante colourlaser 1200 printer, it still say install opc belt.

You probably need to go into the menu structure and find the resets menu. It could be under machine info or maintenance. When you have found the reset menu or parts life, you should be able to reset the OPC Belt.

Error msg appear set belt cg dont know what to do.. am i have to replace the photodeveloper cg?

The error can either be caused by the OPC/OPC Marker assembly or the Main Motor assembly. Please follow the recommended troubleshooting steps:
  1. Power the printer off, remove and reseat the OPC unit, and power the machine back on. Print a test page. If error continues, proceed to step 2.
  2. Power the printer off and remove the OPC unit. Check the OPC Marker Sensor. If it is unsnapped or unplugged, reseat or replug it, and power the printer back on. Print a test page. If error continues, proceed to step 3.
  3. Remove the OPC unit and check it for scratches or defects. Also check the the markers on the OPC to make sure they are not damaged. Is the belt scratched or damaged? If the OPC is at or near the end of its life, OPC unit must be replaced. If the belt is in good condition, contact Lexmark technical support (if printer is under warranty) or your local authorized service provider for assistance.

Replace belt CG

Set Belt CG The OPC belt cartridge needs replacement.

Replacing the Optical Photoconductor (OPC)
Belt Cartridge
Replace the OPC belt cartridge at least once every 12 months, or when
the control panel display indicates that replacement is necessary. The life

color pages), at a 5% toner coverage rate on letter-size paper.

2. Unlock the lever to open the front
cover. This releases the pressure on the
toner cartridges.
3. Unlock the lever to open the top cover
4. Pull the green OPC belt cartridge lock
levers up until they unlock.

5. Pull the used OPC belt cartridge
upward and out of the printer carefully
to avoid spilling toner.
6. Discard the used OPC belt cartridge
Caution! Do not touch or wipe off any powder that is on the OPC belt, nor expose
the OPC belt to light.
7. Remove the two shipping pins from the
new OPC belt cartridge.
8. Remove the protective sheet that covers
the photosensitive belt.
9. Slide the new OPC belt cartridge downward
into both green lock-lever guides
and into the printer carefully.
10. Push the green OPC belt cartridge lock
levers down until they lock.
11. Close the top and front covers carefully
until they both lock.

Brother MFC 9420cn printer message

Check to make certain that the OPC belt is both seated correctly and that it is not damaged as even though it may have what you consider to be sufficient life left in it, if damaged, it needs to be replaced.

Is the massage replace the cg belt the same as the ocp message as i can't see any damage to them at all.

You are correct the 'Belt CG' is the OPC belt cartrige. The mesage advising this item needs to be replaced comes up as the result of a page counter in the printer. The mesage comes up as a result of the page counter exceeding the maximum number of pages expected from the OPC, ensuring reliable print qulaity.
The message does not indicate the OPC Belt is damage, it has reached the end of its designed life.

Press 1 to reset the life counter.
